NAME
     XIntersectRegion, XUnionRegion, XUnionRectWithRegion, XSub-
     tractRegion, XXorRegion, XOffsetRegion, XShrinkRegion -
     region arithmetic

SYNTAX
     cc [ flag... ] file... -lX11 [ library... ]

     int XIntersectRegion(Region sra, Region srb, Region
          dr_return);

     int XUnionRegion(Region sra, Region srb, Region dr_return);

     int XUnionRectWithRegion(XRectangle *rectangle, Region
          src_region, Region dest_region_return);

     int XSubtractRegion(Region sra, Region srb, Region
          dr_return);

     int XXorRegion(Region sra, Region srb, Region dr_return);

     int XOffsetRegion(Region r, int dx, int dy);

     int XShrinkRegion(Region r, int dx, int dy);

ARGUMENTS
     dest_region_return
               Returns the destination region.

     dr_return Returns the result of the computation.  ds Dy move
               or shrink

     dx
     dy        Specify the x and y coordinates, which define the
               amount you want to  the specified region.

     r         Specifies the region.

     rectangle Specifies the rectangle.

     sra
     srb       Specify the two regions with which you want to
               perform the computation.

     src_region
               Specifies the source region to be used.

DESCRIPTION
     The XIntersectRegion function computes the intersection of
     two regions.

XLIB FUNCTIONS                             XIntersectRegion(3x11)



     The XUnionRegion function computes the union of two regions.

     The XUnionRectWithRegion function updates the destination
     region from a union of the specified rectangle and the
     specified source region.

     The XSubtractRegion function subtracts srb from sra and
     stores the results in dr_return.

     The XXorRegion function calculates the difference between
     the union and intersection of two regions.

     The XOffsetRegion function moves the specified region by a
     specified amount.

     The XShrinkRegion function reduces the specified region by a
     specified amount.  Positive values shrink the size of the
     region, and negative values expand the region.
